Go package for splitting strings (aware of enclosing braces and quotes)
The problem with standard Golang strings.Split is that it does not take into consideration that the string being split may
contain enclosing braces and/or quotes (where the separator should not be considered where it's inside braces or quotes)
Take for example a string representing a slice of comma separated strings...
str := `"aaa","bbb","this, for sanity, should not be split"`running strings.Split on that...
package main
import "strings"
func main() {
str := `"aaa","bbb","this, for sanity, should not be parts"`
parts := strings.Split(str, `,`)
println(len(parts))
}would yield 5 (try on go-playground) - instead of the desired 3
However, with splitter, the result would be different...
package main
import "github.com/go-andiamo/splitter"
func main() {
commaSplitter, _ := splitter.NewSplitter(',', splitter.DoubleQuotes)
str := `"aaa","bbb","this, for sanity, should not be split"`
parts, _ := commaSplitter.Split(str)
println(len(parts))
}which yields the desired 3! try on 801D go-playground
Note: The varargs, after the first separator arg, are the desired 'enclosures' (e.g. quotes, brackets, etc.) to be taken into consideration
While splitting, any enclosures specified are checked for balancing!
Quotes within quotes can be handled by using an enclosure that specifies how the escaping works, for example the following uses \ (backslash) prefixed escaping...
package main
import "github.com/go-andiamo/splitter"
func main() {
commaSplitter, _ := splitter.NewSplitter(',', splitter.DoubleQuotesBackSlashEscaped)
str := `"aaa","bbb","this, for sanity, \"should\" not be split"`
parts, _ := commaSplitter.Split(str)
println(len(parts))
}Or with double escaping...
package main
import "github.com/go-andiamo/splitter"
func main() {
commaSplitter, _ := splitter.NewSplitter(',', splitter.DoubleQuotesDoubleEscaped)
str := `"aaa","bbb","this, for sanity, """"should,,,,"" not be split"`
parts, _ := commaSplitter.Split(str)
println(len(parts))
}package main
import (
"fmt"
"github.com/go-andiamo/splitter"
)
func main() {
encs := []*splitter.Enclosure{
splitter.Parenthesis, splitter.SquareBrackets, splitter.CurlyBrackets,
splitter.DoubleQuotesDoubleEscaped, splitter.SingleQuotesDoubleEscaped,
}
commaSplitter, _ := splitter.NewSplitter(',', encs...)
str := `do(not,)split,'don''t,split,this',[,{,(a,"this has "" quotes")}]`
parts, _ := commaSplitter.Split(str)
println(len(parts))
for i, pt := range parts {
fmt.Printf("\t[%d]%s\n", i, pt)
}
}
